Yeah, I think the mathematical exposition was pretty good, but I couldn't bring myself to finish the book because of the culture war she kept trying to shove in.

Are you referring to this book in particular or her writing in general?

I am referring to her other book, The Joy of Abstraction.

Can you elaborate on what you mean by that?

Not the person you’re asking, but the reviews of previous books make similar complaints:

> This is not just a mathematics book, but unfortunately also a polemic of progressive politics. For example, on p.42 there is a helpful definition of “cisgender”, in case you didn’t know. Then, on p.319, the notion of isomorphism — ubiquitous in mathematics, and really quite simple — is explained by considering two categories induced by a partial ordering, one consisting of concepts involving rich, white and male, and another involving rich, white and cisgender. It is then shown that rich white cisgender women have the same status in the second category as rich white males do in the first. Just below this, there is a helpful diagram showing that each of these categories is a 3-fold product of the category consisting of two objects and one arrow, namely (people with structural power —> people who are structurally oppressed). Really, there are many simpler ways to get these ideas across.

Yeah, I try to avoid the culture war stuff, but this seems pretty unnecessary for a math book.

She used the same example in some lecture on youtube, too.
